gnupg-2.0.5 use of if (!vaargs) in estream-printf.c

[Peter O'Gorman]

Hi,
gnupg-2.0.5 fails to compile on at least HP-UX and Tru64 due to its
assumption that a va_list is some kind of pointer.

I simply commented out this code:
 
      if (!vaargs)
        {
          if (read_dummy_value (value, vt))
            return -1;
        }
      else

I can not figure out how the vaargs would be null at this point
anyway, is there a real possibility that it can be NULL?

Thanks,
Peter
